編譯qtopia最好使用的是低版本的gcc和g++. 舉個簡單的例子在qtopia的源代碼中有個函數的使用

? 在qmemoryfile_unix.cpp中int open(const char*, int, ...),這個函數的使用就有問題了。因為open函數需要三個參數，而這里只有兩個，新版本的gcc必須要求傳入三個參數。所以這個會有錯誤。需要修個源碼。。 ? 還有在另外的一個文件中使用strrchr函數時，函數的第一個參數是const型的，新版本g++不支持報錯了。而g++4.1編譯則沒有問題。所以這里我重新安裝了g++4.1版本。 ? 編譯qtopia時候可能還會遇到問題 ? make[1]: Entering directory `/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/src' echo '#include "kernel/qt.h"' >allmoc.cpp g++ ?-c -I/usr/X11R6/include -I/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/include -I/usr/X11R6/include -pipe -O2 -Wall -W -DNO_DEBUG -fPIC -DQT_BUILTIN_GIF_READER=0 -DQT_NO_IMAGEIO_JPEG -DQT_NO_IMAGEIO_MNG -DQT_NO_SM_SUPPORT -DQT_NO_XKB ?-I/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/src/3rdparty/zlib -I/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/src/3rdparty/libpng ?-I3rdparty/kernel -I3rdparty/tools -o tmp/release-shared-linux-g++/tools/qmemoryfile_unix.o tools/qmemoryfile_unix.cpp tools/qmemoryfile_unix.cpp: In member function ‘QMemoryFileData* QMemoryFile::openData(const QString&, int, uint)’: tools/qmemoryfile_unix.cpp:149: warning: format not a string literal and no format arguments tools/qmemoryfile_unix.cpp:152: warning: format not a string literal and no format arguments tools/qmemoryfile_unix.cpp:181: warning: format not a string literal and no format arguments tools/qmemoryfile_unix.cpp:190: warning: format not a string literal and no format arguments tools/qmemoryfile_unix.cpp:235: warning: format not a string literal and no format arguments In file included from /usr/include/fcntl.h:217, ?????????????????from tools/qmemoryfile_unix.cpp:50: In function ‘int open(const char*, int, ...)’, ????inlined from ‘QMemoryFileData* QMemoryFile::openData(const QString&, int, uint)’ at tools/qmemoryfile_unix.cpp:143: /usr/include/bits/fcntl2.h:51: error: call to ‘__open_missing_mode’ declared with attribute error: open with O_CREAT in second argument needs 3 arguments make[1]: *** [tmp/release-shared-linux-g++/tools/qmemoryfile_unix.o] Error 1 make[1]: Leaving directory `/opt/EmbedSky/Qte/x86-qtopia-2.2.0/qt2/src' 解決辦法： 在Ubuntu 9.10上， gcc會嚴格檢查open()的參數傳遞，如果第二個參數為O_CREAT的話(就像qtopia-2.2.0-FriendlyARM/qt2/src /tools/qmemoryfile_unix.cpp的143行這樣)，必須傳入第三個參數mode。因此，手動修改x86-qtopia- 2.2.0/qt2/src/tools/qmemoryfile_unix.cpp 143行 將 ????if (!f) ????????f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY); ??
